(2/3)*(7/8-(4*x))-(5/8) = 3/8 // - 3/8
(2/3)*(7/8-(4*x))-(5/8)-(3/8) = 0
(2/3)*(7/8-4*x)-5/8-3/8 = 0
2/3*(7/8-4*x)-5/8-3/8 = 0
(2/3*8*(7/8-4*x))/8-5/8-3/8 = 0
2/3*8*(7/8-4*x)-5-3 = 0
-64/3*x-3-1/3 = 0
-64/3*x-10/3 = 0
(-64/3*x-10/3)/8 = 0
(-64/3*x-10/3)/8 = 0 // * 8
-64/3*x-10/3 = 0
-64/3*x-10/3 = 0 // + 10/3
-64/3*x = 10/3 // : -64/3
x = 10/3/(-64/3)
